The PCF2129 is a CMOS real time clock and calendar with an integrated temperature
compensated crystal oscillator (TCXO) and a 32.768 kHz quartz crystal optimized for very
high accuracy and very low power consumption. The PCF2129 has a selectable I2C-bus
and SPI-bus, a backup battery switch-over circuit, a programmable watchdog function, a
timestamp function and many other features.
